Application filed September 18, 1915.. Serial No. 51,435.

1 b all whom it may concern Be it known that I, SAMUEL W.v TALIA rnnno, a citizen of the United States, resid ing at San Francisco, in the county of Eian l 'ancisco and State of California, have in vented new and useful Improvements in lllagazineHolders for Abrasive Disks, of which the followingis a specification.

Dentists use frequently and in great numbers abrasive disks of different kinds and sizes. Heretofore, so far as I am aware, no special provision hasbeen made for keeping these disks in such a manner that a disk of each particular size and character is at all times readily accessible to the dentist, but they have been usually placed indiscriminately in a drawer or other receptacle, so that by use they soon became so commingled in the drawer that considerable time was often wasted in extracting from the drawer the desired disk.

The primary object of my invention is to provide a magazine holder by which these disks will be preserved in a manner conveniently accessible to, and selectable by, the dentist.

A further object of the invention is to provide a magazine holder which can be quickly and conveniently replenished with abrasive disks.

Tn the accompanying drawing, Figure 1 is a plan view of my improved magazine holder; Fig. 2 is a broken vertical section thereof on the line 22 of Fig. 1; Fig. 3 is a broken horizontal section of a holder proper detached from the outer casing, showing some magazine chambers filled, and others empty; Fig. 4: is a broken vertical section of the outer casing detached; Fig. 5 is a broken horizontal section-of the said outer casing.

Referring to the drawing, 1 indicates a round casing, a base 2, a cylindrical outer wall 8 extending upwardly from said base and the inner side of which is formed with a circular series of arcuate recesses 4:, a centralraised portion 6, the top of which is concave to form a cup 7, and, between said raised por tion 6 and wall 3 a flat, annular bottom 8 having therethrough two diametrically op posite holes 9. In the annular groove between the central raised portion 6. and the wall 3 is contained a metal holder 10, comand comprising in one piece pris-ingin one piece an inner wall 11, a circular series of vertical partitions 12 extendin radially'from said inner wall, a flange 13 covering the tops of said partitions, and a base 1%. The recesses l in the wall 3 of the outer casing areinthe form of portions of cylinders of diameters suitable to enable the different abrasive disks 5 used by the dentist to fit snugly therein. They are therefore generallymade' of different sizes, and there are a suitable number of each size. The recesses of the same size are intended to receive disks ofdifl'erent characters.

The periphery of thebase 14C of the metal holder is formed with apertured rounded portions 16 which respectively fit snugly within the recesses 4: in the wall 3 of the casing. Above the base and between the partitions the metal 'holder'is formed with cylindrical chambers 17 open on the outer side and of diameters respectively correspending to the diameters of the recesses l in the wall of the outer casing. In the rounded portions 16: of the base are sockets to receive the'lower ends of coiled springs 18. The flange 13 isalso formed with recesses corresponding to the chambers, but of slightly less diameters, the portions of the flange between the recesses being wider than the partitions so that'they engage the edge of the uppermost'of a pile of abrasive disks and prevent their 'upwardfmovement. The upper surface of the wall '8 is formed with channelways 21 lower than the flanges b the thickness of a disk, and by which the uppermost disk of a pile is guided when withdrawn outwardly from the remainder. To the inner surface of the inner wall of the metal holder are secured the upper ends of spring latches 22 which extend down wardly through the holes 9 in the body of the outer casing, and secure said metal holder to said casing. However, these spring latches may, if preferred, be'omitted.

The use of the device will be apparent from the foregoing description. To fill a chamber lTwith abrasive disks, the metal holder is withdrawn, the spring 18 'is pressed downward, and the pile of disks is inserted sidewise into the chamber.

Theutility of'the' device is obvious. The dentist can, at a glance, select the abrasive disk of the kind and size that he wishes to use, and can withdraw the same from the magazine holder by the mere pressure outwardly of his finger on its upper surface. Upon the withdrawal of any disk the remaining disks are immediately pushed up in the hole so that the uppermost disk is in the same position as the one just withdrawn ready for use.

The cup 7 forms a convenient receptacle for keeping mandrels and other tools used by the dentist.

lVhile I have herein referred to the device as being principally for use in holding abrasive disks, this being the purpose for which it was originally intended, it is to be well understood that my invention is not limited to any such use, but any use for which it is found capable or desirable is included therein.

I claim 1. A magazine holder comprising a holder proper having in its periphery cylindrical magazine chambers open on the outer side and a detachable casing surrounding said holder and formed on its inner side with cylindrical recesses of the same diameter as the chambers.

2. A magazine holder comprising an an nular holder proper having in its periphery cylindrical magazine chambers open on the outer side and a casing surrounding said holder and formed on its inner side with cylindrical recesses of the same diameter as the chambers, said casing having a raised central cup-shaped portion extending through the opening in the annular holder. 3. A ,magazine holder for disks having vertical cylindrical recesses open at the outer side, a coiled spring in each recess, the top of the holder having recesses of slightly less diameter than those of the cylindrical recesses respectively, and a detachable casing surrounding the holder and extending opposite to said recesses only to a height less than that of the top of the holder by substantially the thickness of a single disk.

4. A magazine holder for disks having vertical cylindrical recesses open at the outer side, a coiled spring in each recess, the top of the holder having recesses of slightly less diameter than those of the cylindrical recesses respectively, and a detachable casing surrounding the holder formed in its inner side with recesses and extending opposite to said recesses only to a height less than that of the holder by substantially the thickness of a single disk.

5. An annular magazine holder for disks having vertical cylindrical recesses, a coiled spring removably secured in each recess, the top of the holder having recesses of slightly less diameter than those of the cylindrical recesses respectively, and a casing surrounding said holder and having a central cupshaped raised portion extending in the opening in said holder.

6. A magazine holder for abrasive disks comprising a hollow body having a horizontal web extending across its interior and dividing it into upper and lower chambers and having in its marginal portion individual chambers for piles of disks, a coiled spring removably secured in each chamber, and means detachably secured to said body and formed with recesses registering with said chambers, the marginal portion of said means around said recesses being raised above the portions of said body on the outsaid of said recesses substantially the thickness of a single disk.

In testimony whereof I have hereunto set my hand in the present of two subscribing Witnesses.
